I'm impressed by the premium gold packaging of this top quality product. Gone is the bland silver grey which seriously understated this excellent oil. Now its golden colour is announced by its container. If for no other reason, you should switch to Gulf Western because it is proudly manufactured in Australia. Indeed, you'd be surprised by the huge number of products this company produces. Unlike so many companies whose website seeks to conceal, the GW website boldly declares its warehouse in every state.

The bold claim “ Mid-range viscosity reduces oil consumption in vehicles with high previous engine wear”, if anything it gets consumed as much as any other semi synthetic oil, will be switching back to fully synthetic next oil changeBut cheap enough, perfect for your beat up daily if you don’t mind topping up the oil every so often.

Great choice of quality items, then I was given $11 credit, followed by $5 more credit, just because item I bought went on sale a fortnight after. Thanks heaps guys, love shopping here.

I'm picky about oils and their quality. I've used NULON products for my vehicle care and have found them very worthy. This is the first time using Gulf Western oil and from what I see and assess, it is just as good as NULON and is worth the price. I highly recommend using it. And it's an Australian product from what I've been told. Need to research more.
Quality Oil with a decent price tag. The guy could have sold me a more expensive oil but sold me what was in my budget. Very helpful young man
So been the intune mechanically minded guy that i am. I noticed a rattling under the hood of my super hi performance 1998 hyundai sonata.After opening the hood looking around for a few minutes i decided it was the lack of oil was the cause.While the lack of oil ment less crank damping unleashing vital horsepower. I thought oil might help with the noise.How did i choose this oil.I made a informed decision based on all the key factorsBut mostly it was on sale and the cheapest optionOnce i poured this liquid gold in the weapon sonata. Guess what happened the rattle dissapeared.That pesky oil light stopped flashingThe power didnt drop off to muchSo the sonata lives to to fight another day
Not a fan of synthetic oil for my 97 rodeo, but at this price I couldn't resist. Just seems to smoke after about 5-7000ksGenerally the Gulf Western Blue is ideal; no smoking until the 10k mark.
The price of oils seem to be going up, so I'm using a cheaper one. When I pour it in the motor I cant see any difference. When I start the motor and run it,I cant hear any difference. I'm using the old Gulf western oil because the only difference is the price.
Bought for my 2000 Suzuki Ignis. Has not had oil change due to previous owner of car who didnt look after car at all. so I decidEd to change it myself. this oil is value for money. My engine runs smooth now. Good enouh for 20 yrs old car.
